Taiwan-based English tech website OC Heaven has disclosed some performance figures of the upcoming ATI Radeon HD 4890 1 GB graphics accelerator. The tests run are two of the most popular synthetic benchmarks: 3DMark Vantage and 3DMark06. Also disclosed, rather verified, are the card's clock speeds as read by ATI Catalyst Control Center and GPU-Z. The test bed, from what the 3DMark06 window shows, consists of an Intel Core i7 920 CPU running at 2.66 GHz, coupled with 3 GB of system memory. In 3DMark06, the HD 4890 accelerator secured a score of 16,096 points, with SM 2.0 score of 6155, HDR/SM 3.0 score of 7521, and CPU score of 4836. In 3DMark Vantage, it secured a score of P10996. Catalyst Control Center reveals the card's memory bandwidth to be 124.8 GB/s, up from the 111 GB/s on its predecessor, the HD 4870. The early driver in use makes provides "RV790" as the device string to GPU-Z.

Update (03/19):Ukrainian website Overclockers.com.ua has come up with a more comprehensive 3DMark shootout between cards in this segment. Radeon HD 4890 and HD 4890 CrossFireX are part of the comparison. The testers used an Intel Q6600 CPU running on an X48 motherboard with 4 GB of memory. The article can be read (Google-translated to English) here.

I know some of you might want to say that HD4890 is just an overclocked version of HD 4870, but the test results are somewhat convincing. It shows a pretty good improvement in comparison with HD4870. The score on 3DMark06 is very close to GeForce GTX 285, but not on 3DMark Vantage because of the advantage of PhysX that GTX 285 has taken. Will HD4890 be fast enough to compete with GTX 285 in gaming? guess we'll have to see some more test results to be able to tell.

by: alexp999I get a GPU score of about 10,800 which isnt affected by Physx, I thought the 4870 was capable of more than these results show. The 4890 should be even further ahead.

And 8800's score comparable with a 4850, but what do you think does better outside a synthetic benchmark? Don't know about anyone else here, but I play games, I like to benchmark, but end of the day I'd rather play games better.

I suppose, we need to wait until some gaming benchmarks come out then.

Actually we need to wait till ATI provides official drivers for this card, as it is not fully supported yet so obviously the scores are a little low. Give it a couple of months and the drivers will improve substantially, and so will the scores.
